Abstract
An industrial mat that has a support core configured and arranged to support other components of the mat; and upper and lower layers that provide upper and lower surfaces of the mat and that protect the support core. The support core includes a frame of longitudinal side members, end members and cross members each of which is made of steel or a thermosetting plastic material. The frame can include wood, plastic or elastomeric internal members or materials to fill internal open areas of the frame, with the upper and lower layers and the sides and ends of the frame retaining the internal members or materials therein. The mat preferably includes lifting elements of D-shaped rings, O-shaped rings, chains, or cables attached to the upper or lower layer or the support core to provide certified overhead lifting of the mat for installation and reclamation thereof.
